Step 1: Determine the UTF-8 encoding bit layout
The character ϑ has the Unicode code point U+03D1. In UTF-8, it is encoded using 2 bytes because its codepoint is in the range of
0x0080to0x07ff.
Therefore we know that the UTF-8 encoding will be done over 11 bits within the final 16 bits and that it will have the format:110xxxxx 10xxxxxx
Where thexare the payload bits.UTF-8 Encoding bit layout by codepoint range Codepoint Range Bytes Bit pattern Payload length U+0000 - U+007F 1 0xxxxxxx 7 bits U+0080 - U+07FF 2 110xxxxx 10xxxxxx 11 bits U+0800 - U+FFFF 3 1110xxxx 10xxxxxx 10xxxxxx 16 bits U+10000 - U+10FFFF 4 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx 21 bits Step 2: Obtain the payload bits:
Convert the hexadecimal code point U+03D1 to binary:
00000011 11010001. Those are the payload bits.Step 3: Fill in the bits to match the bit pattern:
Obtain the final bytes by arranging the paylod bits to match the bit layout:

Description
The Unicode character U+03D1 represents the Greek letter "Theta" (Greek: Θ, θ), a symbol commonly used in mathematical notation, digital text, and typography. This character is primarily employed to denote the Greek letter theta (θ) within the scope of mathematical equations, scientific notations, and technical documents. In these contexts, it often symbolizes angles, angular velocity, or angles of rotation. The Greek letter theta also holds significance in the field of computer science as part of the algorithmic notation in Big O notation for time complexity analysis of algorithms. While U+03D1's primary usage lies in these technical domains, its presence in text also contributes to cultural and linguistic richness by incorporating ancient Greek script into modern digital communication.
